Title: Plasma display pannel
Inventor: KIM TAE YUN
IPC: H01J11/36
Filed: 1999-06-01
Abstract: PURPOSE: A PDP(Plasma Display Panel) is provided to prevent color mixing caused by fluorescent flow by forming a sidewall having at least wider one of both edges than the center and to prevent a protective film from being damaged by reducing concentration of force on the edge. CONSTITUTION: An address electrode is formed on a rear substrate(20) by Ag, Cr/Cu/Cr or CR/Al/Cr screen printing, photosensitive film paste, sputtering-photolithography or lift-off. A dielectric film is formed thereon. The dielectric film protects the address electrode and prevents light from transmitting the rear substrate. Then, a sidewall(25) is formed to prevent cross-talk between adjacent cells. The sidewall has a lower end of 280 micrometers twice as wide as the central portion and keeps an interval between both edges larger than 100 micrometers for smooth discharging. An RGB fluorescent layer(24) is formed between the sidewalls and the rear substrate is bonded with a front substrate. Fluorescent flows but the edges of the sidewall prevent fluorescent from being mixed

Abstract: PURPOSE: A broadcasting service method is provided to carry out a common broadcasting service by allocating an identical traffic channel to a plurality of users located in an identical cell area. CONSTITUTION: A BTS(Base Transceiver Subsystem) provides service information for a common broadcasting service as a broadcast message to all the users located in an identical cell through a paging channel(S200). The first user attempting call access transmits a mobile origination message to the BTS to request the assignment of a desired common traffic channel(S201). The BTS transmits a null traffic to the first user through a forward traffic channel(S202). The BTS settles a resource of the forward traffic channel to carry out the common broadcasting service and transmits the resource information of the settled forward traffic channel as a channel assignment information notification message to the first user through the paging channel(S203). The user, receiving information for the settled forward traffic channel through the channel assignment information notification message, recognizes a forward common traffic channel using null traffic information transmitted through the settled forward traffic channel. The first user drops a backward traffic channel and doesn't transmit a preamble(S205). The BTS transits a call setup state for the forward traffic channel to a call connect state and starts broadcasting service through the connected forward traffic channel(S206).
